Coulomb's formula F = KQ₁Q₂/R² gives the force between two charges in free space. The value of K

Question

Quizplus · Accepted Answer

The value of K, also known as Coulomb's constant or the electrostatic constant, is a fundamental constant of nature and is the same under all circumstances. It is approximately equal to 9 x 10^9 Nm^2/C^2. Choice B is incorrect because K depends only on the medium in which the charges are located, not on their polarity. Choice C is incorrect because K does not depend on the masses of the charged particles. Choice D is incorrect because K is not equal to the charge on the electron.
